Description
Technical field
The utility model relates to the measuring tools more particularly to a kind of section of jurisdiction faulting of slab ends measuring equipment in a kind of shield-tunneling construction.
Background technique
In Shield Construction Technique, molding tunnel quality is to measure the important evidence of quality of main body project, forms tunnel matter
Measuring parameter includes the projects such as section of jurisdiction infiltration, breakage, faulting of slab ends, ovality, elevation, horizontal position, and section of jurisdiction faulting of slab ends is as molding tunnel
The important items for acceptance that road is checked and accepted, it is necessary to which 100% qualification rate for reaching design and code requirement could pass through the acceptance of work.Section of jurisdiction
Faulting of slab ends is the dimensional discrepancy formed between the adjacent section of jurisdiction of same ring or adjacent ring section of jurisdiction after the completion of assembly, influences faulting of slab ends size
It is many because being known as, such as: shield attitude, segment bolt degree of tightening, synchronous grouting, stratum rich water situation etc., the palm promptly and accurately
Gripping tube piece faulting of slab ends data be analysis shield-tunneling construction parameters and hidden project whether He Ge important evidence.
The shield duct piece faulting of slab ends method for measurement of the prior art mostly uses Steel Ruler auxiliary clearance gauge to be measured, and principle is benefit
Gap value is converted by faulting of slab ends value with Steel Ruler, then clearance gauge is recycled to measure gap value, as section of jurisdiction faulting of slab ends value.In adjacent tubes
In the case that piece cambered surface is uneven, first by Steel Ruler along the section of jurisdiction cambered surface for being tightly attached to protrusion perpendicular to circumferential weld or longitudinal joint direction
On, then clearance gauge is filled among the gap of Steel Ruler and another section of jurisdiction cambered surface, is finally section of jurisdiction in the value that clearance gauge is read
Faulting of slab ends value.The measuring tool and method of the prior art have the following disadvantages:
1, when measuring section of jurisdiction faulting of slab ends, since the measurement principle of clearance gauge need to fit in clearance gauge in lower section of jurisdiction cambered surface,
Steel Ruler abuts against on the section of jurisdiction of protrusion, but section of jurisdiction be cambered surface and clearance gauge be it is linear, cause section of jurisdiction cambered surface and clearance gauge cannot
It fits closely, so as to cause the error measured；And clearance gauge length is longer, then fitting is not close, and error also will be bigger, leads
Cause the data measured that can also have error, it is inconvenient to measure, and needing both hands to carry out operation could complete.
2, it during measurement, needs to take Steel Ruler on the other hand, takes clearance gauge on the other hand, it is inconvenient, and for leaving and taking image
When data, the second people is needed to cooperate, labor intensive.
Utility model content
The purpose of this utility model is to provide a kind of section of jurisdiction faulting of slab ends measuring equipment and methods, keep measurement tasks convenient, fast
It is prompt, simple, error in measurement and measurement tasks intensity are reduced, tunnel is formed for shield and provides faulting of slab ends data accurately and timely,
Can targeted assistant analysis faulting of slab ends reason formation, construction parameter easy to adjustment in time determines faulting of slab ends remedial measure, is
The molding tunnel of high quality provides foundation early period.
The utility model is realized in this way:
A kind of section of jurisdiction faulting of slab ends measuring equipment, including the first measurement ruler and second measure ruler, and first, which measures ruler and second, measures
Ruler is with graduated ruler；0 scale line end of the first measurement ruler is connect with 0 scale line end of the second measurement ruler, the first amount

The utility model compared with prior art, has the following beneficial effects:
1, the utility model reacts faulting of slab ends by the short right-angle side and long right-angle side of right angled triangle or the ratio of bevel edge
Value, greatly simplify measurement process, improve the efficiency and precision of measurement tasks.
2, the utility model can adjust the precision of measurement by changing the angle of two measurement rulers, widely applicable, and two
The angle θ for measuring ruler is preferably 5.74 °, accuracy in measurement can be increased to 0.1mm, forms tunnel for shield and accurately may be used to providing
Reference frame.
3, the utility model using two with graduated measurement ruler, it can be achieved that bidirectional measurement, while common amount can be also served as
Ruler to be surveyed to use, a ruler is multi-purpose, it can also be used the vernier caliper of repacking as the measurement ruler of the utility model, convenient for drawing materials,
It is at low cost.
The utility model utilizes trigonometric function principle, and faulting of slab ends value is directly transformed into the right angle of triangle using mathematical relationship
Side or bevel edge conveniently can directly be read, and solve the not close caused error of fitting in existing section of jurisdiction faulting of slab ends measurement technology
Greatly, the disadvantages of precision is low, inconvenient for operation, tool construction is complicated is not needed to convert faulting of slab ends value to the measurement of gap value, be reduced
Multiple tools physical transformation bring data error is bonded not tight and generates between clearance gauge and section of jurisdiction cambered surface when eliminating measurement
Error simplifies the operating process of existing method for measurement, keeps shield duct piece faulting of slab ends measurement tasks convenient, fast, can also be according to not
Same accuracy in measurement requires to be adjusted.
